Spatial modeling of landscape processes

Path sampling method: accuracy and properties

Error is proportional to the 1/N^1/2, where N is the number of samples

**number of samples sediment flow erosion/deposition**
70,000 (~1 per cell)
50 milion or 50K run on 1000 processors

movie Properties:

no mesh is needed (can be used with standard GIS formats)

computationally demanding but perfectly scalable for parallel architectures

robust and flexible: multidimensional, multiscale
